Randomized Study of the pdSTIM™ System in Failure to Wean Mechanically Ventilated Patients (ReInvigorate)

The pdSTIM Pivotal Study (ReInvigorate Study) is a prospective, multicenter, randomized, controlled clinical study to evaluate the safety and efficacy of the pdSTIM System to facilitate weaning from mechanical ventilation through phrenic nerve stimulation. Potential subjects who are on mechanical ventilation for ≥ 96 hours (4 days) and have failed at least one weaning attempt will be considered for the study. Those enrolled will be randomized in a 1:1 manner between a Treatment group that is standard of care with the pdSTIM System and a Control group that is standard of care only. For the Treatment group, stimulation therapy with pdSTIM will occur daily until the subject is successfully removed from mechanical ventilation or the 30-Day follow-up visit, whichever is sooner. All randomized subjects will be followed to 60 (± 7) days post randomization. Total subject participation will be no longer than 67 days.
